The Runaway Potters (up for adoption)

Prologue

AN: this is my first Fanfic, and all characters that are in the canon series unfortunately aren't mine, but the amazing J.K. Rowling.

I walk down the path towards the mansion, Potter mansion while holding the 2 birthday presents. All while thinking things like, 'show off', 'curse you Potter!' And the like.

Oh by the way, my name is Severus Snape. I am 25 years of age, the youngest ever potions master, the professor for potions at Hogwarts, and James Potter's favourite person to tease.

The reason I am walking to his mansion with presents is because I was his wife's, Lily, best friend years ago. That all went away when I made a mistake 10 years ago. I tried to apologise multiple times but she never forgave me, until a month ago.

She told me that she forgives me for calling her a mud blood all those years ago, but we will never have the same relationship. She also told me to come to her sons birthday today.

So here I am. Walking with a present for Harry Potter and his twin Chris Potter, the boy-who-lived. I haven't met the two boys, or their big sister Evelyn or their little sister Rose, but from what I've heard from Lily and Albus is that Chris is intelligent, kind, good, honest, brave and has a great control over his magic.

While his siblings are the complete opposite. Apparently they are always getting into trouble, have no control over the limited magic they have used accidentally, always blaming Chris for stuff and always being bullies to Chris.

Anyway, I reach the gate. It is large and majestic looking and has the Potter crest in the middle, so it splits in half when it opens. It is gold and has spikes on the top to stop burglars.

I knock. I stand there for a few minutes as I listen to all the commotion going on. I hear screaming, splashes and adults talking.

After a while the gate opens to Black. He looks at me. "Come on in Snape." He welcomes me.

"Thank you Black." I reply as I walk through the gate. "Big enough party?" I ask quietly as I take in the scene in front of me.

There is a big 30m pool with loads of pool toys and children in it, kids flying on toy brooms, kids playing party games, kids eating and the adults talking at the table. There are easily 150 kids between 2 to 9 there and about 100 adults.

"Yeah. Chris is spoilt." He hesitantly answers. "And he's the boy-who-lived so others wanted to come. Lily and James let them of course."

I look at him, once again struck by how different he is to what he use to be. Black was a prankster at school, and he loved to bully slytherins, especially me. He was a good for nothing brat along with Potter. Lupin and Pittergrew weren't as bad as them. Black once tried to have lupin kill me in 6th year in fact. Lupin is a werewolf and black lead me to where he was on the full moon.

After school he was still bad news but he started dating Amelia Bones about 6 years ago and he started to mature a lot. He even apologised to me. We of course aren't besties, but we have gone from rude nick names to our last names.

"Where are your girls Black!" I ask him.

He smiles and replies. "Follow me."

I do and he takes me to the centre table where I see Potter, Lily, Lupin, Augustus Longbottom and a hugely pregnant Amelia Black chatting quietly.

Black goes to his wife and places his arms around her and kisses her cheek. Everybody looks at him and then to me.
"Um, hi." I greet them.

They wave to me except Potter. He has a look of disgust on his face. "What are you doing here Snivellus?" He spits out to me.
